The problem with your argument is that it is locked in the trap of rationality.

Yes it is often rational for women to seek hypergamy and it is often rational for a woman to cuckold their husbands with a higher status male. Similarly it is rational for men to sleep around, cheat on their wives, and father children beyond their ability to support.

This rationality is ultimately self-destructive. The only long term solution is to elevate the nature of the participants. The problem vanishes among the superrational.

See: Superrationality and the Infinite for my prior post on superrationality.

I have seen you post arguments that women are ruled by their base desires and cannot be superrational. This is probably true of many women as it is true of many men who face an equally difficult struggle. Controlling our primal urges versus letting them control us is a lifelong struggle for all of us male and female alike. Sometimes we fail.

Ultimately the rational face inevitable decline at the hand of their own choices. In this case the consequences are already showing themselves as rational "empowered" females increasingly find themselves unable to find quality husbands and fathers and rational "empowered" men increasingly refuse marriage and fatherhood. Both thus find themselves uncompetitive. The minority that embraces superrationality will expand to take their place eventually becoming the majority a process that is already well underway.
